100 years ago perhaps 1% of Canadians would have described themselves as non-religious. Today, between 10-20%. I think you can see where this trend is headed. Europe is already over 50% in some countries.
16% world wide.

Even in the US, those of "no religion" have grown from 8.4% in 1990 to 15% in 2001, with a numerical growth of 105.7%.

Today, just 21 percent of Europeans say religion is "very important" to them, according to the most recent European Values Study, which tracks attitudes in 32 European countries. A survey by the Pew Forum on Religion and Public Life found that nearly three times as many Americans, 59 percent, called their faith "very important."
Although a Gallup poll found last year that 44 percent of Americans say they attend a place of worship once a week, the average figure in Europe is only 15 percent, although the picture varies widely across the Continent.
